Acid Rain Summary

What it is:
•the deposition of acidic components in rain, snow, dew, or dry particles. •more accurate term is "acid precipitation."
•defined as any type of precipitation with a pH that is unusually low The Causes:•occurs when sulfur dioxide and nitrogen oxides are emitted into the atmosphere, undergo chemical transformations and are absorbed by water droplets in clouds •then fall to earth as rain, snow, mist, dry dust, hail, or sleet. •Dissolved carbon dioxide dissociates to form weak carbonic acid giving a pH of approximately 5.6 at typical atmospheric concentrations of CO2 •Therefore a pH of less than 5.6 has sometimes been used as a definition of acid rain The Effects:

•increases the acidity of the soil, and affects the chemical balance of lakes and streams •accelerates weathering in carbonate rocks and accelerates building weathering •contributes to acidification of rivers, streams, and forest damage at high elevations •When the acid builds up in rivers and streams it can kill fish Problems:

• large fraction of which are formed from the same gases as acid rain (sulfur dioxide and nitrogen dioxide), have been shown to cause illness and premature deaths such as cancer and other deadly diseases •killing off insect and aquatic lifeforms as well as causing damage to buildings and having possible impacts on human health •cause damage to certain building materials and historical monuments •cause weathering on ancient and valuable statues and has caused considerable damage •sulfuric acid in the rain chemically reacts with the calcium compounds in the stones (limestone, sandstone, marble and granite) to create gypsum, which then flakes off •commonly seen on old gravestones where the acid rain can cause the inscription to become completely illegible •causes an increased rate of oxidation for iron

•Visibility is also reduced by sulfate and nitrate in the atmosphere Solutions:
•many coal-burning power plants use Flue gas desulfurization (FGD)...

...﻿Cause and Effect on AcidRain
Introduction
Beautifully crafted statues are now worn out or severely damaged, aquatic wildlife population are dying off, forests have lost the leaves that protect their trees and produce food, and the rates of lung diseases in humans are rising around the world. The cause of all of these problems can be linked back to acidrain. Most people don’t understand the concept or science behind acidrain. The common belief is that it’s a natural process, but it’s actually caused by pollution and human activity. Acidrain affects us all, and people need to understand and recognize that acidrain is a problem.
What Is AcidRain?
Acidrain is also called "acid deposition" and it is acidic precipitation with a pH lower than 5.6. The pH is a scale used to measure acidity where the lower the number, the more acidic a substance. Pure water has a neutral pH of 7.0, while normal surface water is slightly acidic with a pH of 5.6. Humans or natural occurrences can cause acidrain. For example, when a volcano erupts, it releases sulfur dioxide as one of the main components, which can enter the water and cause it to become acidic. However, the primary source of acidrain is the acidic...

...AcidRain
Within this past century, acidity of the air and acidrain have become
recognized as one of the leading threats to our planet's environment. No longer
limited by geographic boundaries, acid causing emissions are causing problems
all over the world. Some laws have been passed which limit the amount of
pollutants that are released into the air, but tougher legislation must be
implemented before this problem can be overcome.
Acidrain is produced, when automobiles, smelters, power plants, and
other industrial factories burn fossil fuels such as gasoline, coal, and fuel
oils. When combusted, the non renewable resources release pollutants such as
sulfur, carbon and nitrogen oxides into the air. These oxide combine with the
humidity in the air and form sulfuric, nitric and carbonic acid. This acidic
solution eventually condenses in the air and comes back down to the earth in any
from of precipitation (snow, rain, hail).
Upon returning to the earth, the acidic precipitation can have serious
repercussions on both the environment and as well as human structures. On
average, acidrain is about nine times more acidic than rain water, and has been
recorded as low as 2.5 on the pH scale (forty times more acidic than water.)
Acid deposition kill fish, soil bacteria, and as well as aquatic...

...AcidRain is a major threat to our environment. It considers being a main issue in the developing countries of Eastern Europe such as Czech Republic, Germany, and Poland. AcidRain is a form of air pollution that comes from the use of gasoline and diesel, fossil-fuel-fired electric power plants, industrial bodies, and residential furnaces by human beings. It also comes from natural hazards such as smoke from forest fires and volcanic eruptions. AcidRain is a major cause of deforestation, and a risk to humans’ health in Czech Republic because of the base of its economy. This essay will focus on the causes, the effects, and the solutions to the acidrain problem that is facing the Czech Republic and its citizens.
First of all, Czech Republic is a landlocked country that used to be part of the Czechoslovakia, in which was emerged and formed from Austro-Hungarian Empire by Czech and Slovaks following World War I. Geographically speaking, Czech Republic is located in the Central Europe, southeast of Germany with temperate; cool summers; cold, cloudy, and humid winters. Czech Republic has few natural resources such as graphite, timber, kaolin, clay, and hard/soft coal (Czech Republic).
Furthermore, Czech Republic’s economy is based on some of the major causes of “acidrain” which are land mines, melting minerals, heavy industries,...

Introduction
I. What would you do if you knew poison was falling from the sky? What would you say if you knew that we were a big part in causing the deaths of many animals, forests, and people? How would you react if I told you that this morning you contributed to atmosphere desolation?
II. Well, get ready to do, say and react because I’m going to tell you that you are, I am, and everybody contributed to acidrain, a deadly and a real accident.
III. But not all hope is lost. We can help by learn and teach about the effects on our environment from more become harmful.
IV. Based on ‘Robert Angus Smith - the scientist who first used the term acidrain - wrote:
a. "It has often been observed that the stones and bricks of buildings crumble more readily in large towns where much coal is burnt.... I was led to attribute this effect to the slow but constant action of acidrain."

What’s the acidrain?
Acidrain is a rain or any other form
of precipitaton that is unusually acidic.
What causes acidrain?
Acidrain is caused by the burning of fossil fuels.
Burning oil, gas and coal in power statons releases
Sulphur Dioxide into the atmosphere. Burning oil
and petrol in motor vehicles puts nitrogen oxides
into the atmosphere.
These gases mix with water droplets in the
atmosphere creatng weak solutons of nitric and
sulphuric acids. When precipitaton occurs these
solutons fall as acidrain.
History of acidrain
Though acidic rain was
discovered in 1852, it was
not untl the late 1960s
that scientsts began Widely
observing and studying the
phenomenon. The term
"acidrain“ was coined in
1872 by Robert Angus Smith.
During the last decade, acidrain has been a major concern
because it contnues to
contaminate large areas of our planet.
Acidrain occurs in the areas of major industrial
emissions of sulfur dioxide and oxides of
nitrogen .

...intent of this paper is to educate individuals about acidrain, define its chemical makeup, and describe its impact on the environment.
Rain is an important part of all life; it is the source of water for almost everything. In some areas rain is actually a threat to life because of pollution from cars, factories, and power plants. This pollution releases gases into the atmosphere to create acidrain. Acidrain is rain, or any other form of precipitation that is uncharacteristically acidic, which means that it possesses a high level of hydrogen ions. This elevated level can have a harmful effect on many different things in the ecosystem. Acidrain poses a serious environmental problem that affects large parts of northeastern United States, and southeastern Canada, as well as parts of Europe (Briney). It has taken such a toll on the environment that government agencies have attempted to make efforts to reduce the amount of pollutants that are released into the atmosphere.
Acidrain, or acid precipitate, is any form of precipitation that has high levels of sulfuric and nitric acids (Briney). Acid precipitate does not always have to be rain, it can be in the form of snow, fog, and small particles of dry material that settle to earth....
